MOLD FOR CASTING WINDOW-WEIGHTS.

SPECIFICATION forming part of Letters PatentNo. 402,558, dated May '7, 1889.

Application filed December 19, 1888. Serial No. 294,069. (No model.) g

To all whom it mayconoern:

Be it known that I, LUTHER G. Boron, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented certain new and useful Improvements in Molds and Flasks for Casting Window and other Weights; and I do declare the following to be a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention has relation to improvements in molds and flasks for casting window and other weights; and it consists in the novel construction and arrangement of its several parts hereinafter set out in the specification and claims.

In the accompanying drawings, Figure 1 is a perspective view of the follow-board. Fig. 2 is a perspective view of one half of the flask and the patterns in position on follow-board.

Fig. 4' is a horizontal section of one half, O,. of

the flask after having been rammed with sand, then having the patterns removed and the stops 1 and chills 2 (the stops and chills being shown in section) put in place. Fig. 5 is a vertical sectional View of the flask and mold thcreimwith the stops 1 and chills 2 in position and ready to receive the molten iron. It is represented as if out through on the line m w of Fig. 4, provided'said Fig. 4. was mounted with the other half of flask rammed with sand. Fig. 3 is a longitudinal sectional view of one of the weights cast in said molds. Fig. 6 is a view of stop 1 and chill 2, while Fig. 7 is a view of the adjustable guide 3.

My invention is.described as follows:

A represents the follow-board, having the longitudinal grooves or recesses a. This follow-board may have as many recesses a as desired, as I may cast from one to a dozen or even more weights at the same running. These grooves are effected by the strips a, securedon' base A. This follow-board is put down level on a solid plane, and the adjustable guides 3 are laid in the recesses a about equidistant from either end of 'the same.

Then the patterns B are laid down in said recesses, their rounded ends fitting in the con and its contact with the ends of the patterns will hold it in place. The half 0 of the flask is then put in position, as shown in Fig. 2. The sand is then packed in. Then the Whole is turned over and laid carefully down on a solid plane. The follow-board is then taken off and parting-sand put on the half-mold.

Then the other half, D, of theflask is put on the half 0, the gate-pin 6 set,-and the flask rammed with sand. Then the patterns B are carefully withdrawn before removing the top part of the flask, which saves from rough joints] and gives speed in working. Then take off the upper half, D, of the flask and remove the gateway-mold 5 and gate-pin 6, put in the stops 1 and chills 2, (see Fig. 5,) and I am ready to cast the weights.

By my invention I am able to cast quite a number of weights at'the same running. I am able to cast them all of the same size and of the same length. I may, however, put the adjustable guides nearer to one end of the follow-board than to the other, and thereby cast one half of the weights long and the other half short; or I may put all of the adjustable guides in the middle of said follow-board, and I may vary the lengths of the weights by the position of the stops 1 and chills 2. (For example, see Fig. at.) I have a rule with guidefigurcs marked on it, by which I can set the stops in the molds to make a casting of any weight desired. Thus, if my flask is large enough to hold twelve patterns, I can at one casting run twelve weights, all of different lengths.

The stops 1 and chills 2 are made of iron, last a long time, and come out of the weights easily after the casting. The points on the stops 1, in connection with chill 2, combine to produce openings 7 and 8, by which the weights are hung or attached to the ropes. The inner ends of the stops 1 are out concave, so as to round the upper end of the weight. The point of the stop is cone-shaped, so that it may be easily withdrawn from the weight.

The chill 2 is also cone-shaped for the same purpose:

Having described my invention,what I claim as new, and desire to secure by Letters Patent, 1s-

1. The combination of the follow-board A, having recesses a, flasks O 1), adjustable guides 3, having the concave ends 4, patterns B, stops 1, having the concave inner ends and cone-shaped points, cone-shaped chills 2, gatepattern 5, and gate-pin 6, all substantially as shown and described, and for the purposes set forth.

2. The combination of the flask, a groove follow-board, patterns, and the guides 3,11aving concave ends 4, as set forth.
